Other objects of the invention will appear hereinafter, the novel features. and combinations being set forth in the appended. claims.

In the accompanying drawings,

Fig. 1 is an elevational view of the discharge end of a shuttle car incorporating the features of my invention; and

Fig. 2 is a sectional view showing the details of the drive for the electric cable reel.

This application is a division of my application, Serial No. 789,384, filed December 3, 1947, entitled Shuttle Car, now Patent No. 2,599,061, dated June 3, 1952.

Fig. l of the drawings shows the discharge end of a shuttle car including a main frame or body In having supporting wheels, one of which i seen at H, and a discharge boom [2. The complete shuttle car is disclosed in my Patent No. 2,599,061 above identified.

Adjacent the discharge end of the shuttle car and generally to one side of the center line of the main frame or body It! and below at least a portion of the discharge boom l2 there is an electric cable reel 13 of relatively large diameter which is mounted for rotation on a generally upright axis. The cable reel I3 is relatively thin, measured along its axis of rotation, so that it may be positioned below the discharge boom l2 vide improved mechanism of the above mentioned and within the confines of the main frame or body It without unduly restricting the clearance of the main frame or body 10.

The cable reel 53 is adapted to receive an elec trical cable It. An electric or hydraulic motor It drives said cable reel i3 through gearing which includes a generally upright shaft 16 having a sprocket I! that rotates upon an axis that is parallel with the axis of rotation of the cable reel l3. Sprocket I! meshes with an endless roller chain 58 anchored to a circular shrouding guide is which is rigidly attached to the top plate of the cable reel it, as clearly illustrated in Fig. 2 of the drawings.

From 2 of the drawings it will be seen that the chain It is secured directly to a top her 24. Therings 22 and. 23 and spacer member 24 are secured directly to the top plate or side member 21 of the cable reel l3 by a plurality of bolts, one of which is seen. at 25. The rings 22 and 23' are each grooved in their facing or adjacent sides as seen at 28 and these grooves hold the chain in a circle. having the same. axis of rotation as the cable reel. It will be seen that when the chain l8 and shroud l9 are assembled and bolted to top plate. 2|. of cable. reel i3 that the shroud causes the chain to form'an internally toothed gear with which the sprocket l1 meshes to rotate the cable reel 13. The chain I8 is secured against rotation in the shroud I9 by one Or more pins 2'! that are anchored to the chain It and extend into openings in the top ring 23.

A clearly illustrated in Figs. 1 and 2 of the drawings, the electric cable reel I3 is mounted for rotation on a generally vertical or upright but inclined axis and a substantial portion thereof extends below the boom l2 and the conveyor of the shuttle car (not shown). This makes possible the employment of a relatively large reel which can handle a great length of electric cable 14 which is reeled thereon, while permitting a relatively wide conveyor or body It in the interest of high capacity and a body that has ample ground clearance adjacent the cable reel. This construction of the cable reel also does not interfere with the low overall height of the shuttle car which is an important characteristic of a shuttle car which may be used in low seam coal. The cable I4 is adapted to extend rearwardly from the vehicle, as illustrated in Fig. 1 of the drawings, or it may extend forwardly by being reeved around a guide sheave or roller 20.

Obviously those skilled in the art may make various changes in the details and arrangement of parts without departing from the spirit and scope of the invention a defined by the claims hereto appended, and applicant therefore wishes not to be restricted to the precise construction herein disclosed.

Having thus described and shown an embodiment of the invention, what it is desired to be secured by Letters Patent of the United States is:

l. A shuttle car including a frame, traction means supporting one end of said frame, a generally horizontal discharge boom extending at said one end and adjacent the top of said frame, a cable reel of relatively large diameter and small axial dimension located within the confines of said frame and below said discharge boom, means mounting said cable reel for rotation on a generally upwardly inclined axis, driving means for said cable reel including a motor and a drive sprocket, means mounting said drive sprocket.

tical axially spaced rings grooved to receive said f chain and hold it in a circle having the axis of rotation of said cable reel as a center, and means f securing said shroud means and said chain to said cable reel.

2. A shuttle car including a frame, traction means supporting one end of said frame, a generally' horizontal discharge boom extending at said one end and adjacent the top of said frame, a cable reel of relatively large diameter and small axial. dimension located within the confines jof said frame and below said discharge boom, means mounting said cable reel for rotation on a generally upwardly inclined axis, driving means for 1 said cable reel including a motor and a drive sprocket, means mounting said drive sprocket for" rotation on an axis extending substantiallyparallel to the axis of rotation of said cable reel, a a chain with which said drive sprocket meshes;

and shroud means attaching said chain to said cable reel including a ring holding it in a circle having the axis of rotation of said cable reel as a center.

3. A shuttle car including a frame, a generally horizontal discharge boom extending at one end and adjacent the top of said frame, a cable reel of relatively large diameter and small axial dimension located within the confines of said frame and below said discharge boom, means mounting said cable reel for rotation on a generally upright axis, driving means for said cable reel including a motor and a drive sprocket, means mounting said drive sprocket for rotation on an axis extending substantially parallel to the axis of rotation of said cable reel, a chain with which said drive sprocket meshes, and means attaching said chain to said cable reel holding it in a circle having the axis of rotation of said cable reel as a center.
